The short answer is results will vary….but a long time! Because of all of the different situations out there, we do not guarantee a time period. The 25oz bottles hold ice cold for approximately 18 hours. Some tell us about how they left their Thinksport bottle in the car in 100 degree weather only to return to clinking ice five hours later. Others tell us how we kept their drinks cold for longer than 24 hours. One customer even put our bottle in a thermal testing chamber and reported that it was the best bottle he had ever seen. On average the sports bottles hold contents hot for 4 hours. Because of the double-walled construction you also won't feel the temperature of the products. So its important to be careful if you've placed hot liquids into the bottle.

Do your bottles fit in cup holders or water bottle cages?

Our 350ml/12oz and 500ml/17oz bottles are designed to fit in car cup holders while our 750ml/25oz bottles fit some (but not all).

12oz and 500ml bottles will fit into water bottles cages. The 750ml fits most bottle cages on spin bikes.

The perfect all around bottle! Great for....

Having cold / hot beverages at the office.

Going for hikes or camping.

Throwing into the backpack for school.

Your yoga, cross-fit or spin class holder of lifesaving water.

A companion while you work in the garden.

Long road trips to your in-laws.

Bedside for late night dry mouth situations.

Thinksport bottle construction:

The bottles are double-walled stainless steel. The mouth piece is made from polypropylene. We would not advise drinking directly from a metal top. The collar of the bottles and the screw on cap are encased in stainless steel.

There is an internal silicone washer. There is no liner inside the bottle or chemical coatings. The bottles are tested for chemicals like BPA, phthalates, heavy metals and biologically harmful chemicals.

What type of stainless steel do you use?

Our bottles are made of 18/8 medical-grade 304 stainless steel and do not have any type of liner.

What are the dimensions of your bottles?

750ml (25oz): 10” high x 3” wide

350ml (12oz): 8” x 2.5” wide

Where are your bottles manufactured?

Our sports bottles are made in China. To proactively address any potential concerns, we’ll mention that all of our products adhere to our strict chemical policy. The Thinksport bottles have been and continue to be tested globally to insure their safety. In fact, our bottles undergo rigorous chemical and biologic testing from multiple laboratories to insure that they do not contain or leach toxic chemicals. Furthermore, Whole Foods has audited our facilities for compliance in Good Manufacturing processes. Regarding quality, the thinksport bottle has been thoroughly field-tested since our inception over four years ago with excellent results.

How do I care for my Thinksport bottle?

While we recommend hand washing our bottles, they are dishwasher safe. We would recommend lodging the strap so that it doesn't get caught by the rotor.

Please note that we do not use Lead in our paint. While you might think that this is obvious, the test for Lead in Europe and the US allows for low levels of Lead. The type of test also measures what is coming off the bottle in a solution, which could easily be nothing. We test the paint in its wet state, which produces test numbers that are accurate depictions of what is in the paint. Do not use any abrasives on the outer surface.

Why a sport bottle?

When we introduced the Thinksport bottle over 8 years ago, most reusable bottles were made of polycarbonate material, which leaches Bisphenol-A (BPA). More recently, it has been shown that aluminum bottles with epoxy liners also leach this harmful chemical. So we first and foremost set out to find a safe material that adhered to our strict chemical policy. All Thinksport bottles are made of 18/8 medical- grade stainless steel. We then went on to design our bottles to be highly functional and great-looking too!

How is the Thinksport bottle different?

All Thinksport bottles are super insulated to keep the contents cold or hot for hours. You can fill our bottle with ice and your favorite drink and enjoy a cold drink without the bottle sweating all over your gym bag, backpack, or desk. All of our bottles also feature a wide mouth opening (for ease of filling and cleaning) and a smaller polypropylene spout (for convenient drinking). We’ve also built in unique functionality like an interior mesh filter that keeps ice from blocking the drinking spout and allows users to brew tea on the go. So, you get a high-quality insulated sport bottle for about the same price as the other guys’ basic single-walled bottles.

Since our company's inception, we have been focused on being socially responsible. For us this means three things:

Create safe products

Have the least impact possible on the environment in the creation, packaging, usage, and disposal of product possible.

Connect to non-profit organizations engaged in activities that help the world become a safer, healthier place

Over the last 7+ years, we have provided products for various fundraisers for diabetes, child abuse, autism, and cancer organizations, and have provided direct aid to catastrophes such as the Texas fires and Haiti. In addition, we have been proud donors to Texas4000, Healthy Child Healthy World, Environmental Working Group, and St. Jude.

Our program evolved, and through a little bit of "thinking," Thinksocial was created. We came up with Thinksocial as a way to empower consumers to choose which non-profits they feel most connected to and want to monetarily support. We call it the democratization of social responsibility.
